PATH_COORD_MAX

It is found that thorvg cannot handle large coordinates well. When the coordinates are larger than 4096, the calculation of tvgSwRle module will overflow in 32-bit system. So we use FLT_MAX and FLT_MIN to write the mark to bounding_box to tell vg_lite_tvg not to add clip path to the current path.
